Python is a widely used programming language that allows developers to work quickly and integrate systems effectively. It is a general purpose, high-level, interpreted, and cross-platform language. Many large companies use Python, including Google, Facebook, Microsoft, and NASA. The introductory session covered installing Python, writing basic print statements and functions, working with objects, lists, modules, conditions, loops, and more Python concepts. Code examples were provided to demonstrate the core features of the Python language.

Charming Python An introductory session on the Python programming language!
Python: A quick look! Python is a programming language that lets you work more quickly and integrate your systems more e鍖ectively. You can learn to use Python and see almost immediate gains in productivity and lower maintenance costs. General Purpose High Level Interpreted Multi paradigm programming Fully dynamic typing Cross Platform CPython, Jython, IronPython (CPython != Cython)
Who uses Python? Google, NASA, Facebook , Yahoo!, Microsoft, Oracle, Nokia, Reddit, Canonical, Walt Disney, Astra Zeneca, Lucas鍖lm All the cool kids are using Python!
Enough Talks! Installing and running python codes *nix and *nix alike system users - sit back and relax! Windows Users: Go to Python.org Get the Python 2 installer Install it yourself Add python to your system path
Show me the codes! Lets say hello to the big snake! print "hello python!" How about a function? def say_hello(name): print "Hello " + name + "!" say_hello("python")
Let there be Objects! class TheGreeter: ! def __init__(self, name): ! ! self.name = name ! def greet(self): ! ! print "Hello " + self.name + "!" greeter = TheGreeter("Python") greeter.greet()
Python Comments! """class TheGreeter: ! def __init__(self, name): ! ! self.name = name ! def greet(self): ! ! print "Hello " + self.name + "!" """ greeter = TheGreeter("Python") #greeter.__init__("masnun") greeter.greet()
Lists! id_list = [1,2,3,4,5,6,7,8,9,10] # Indexing print id_list[1] # Add to list id_list.append(11) print id_list # Remove from list id_list.remove(11) print id_list # Slicing new_list = id_list[0:2] print new_list # List Comprehension another_list = [x for x in id_list if x > 5] print another_list # All those squares! print [x**2 for x in id_list]
Introspection at its best! using dir(), help() and pydoc
Conditions and For Loop In the case of the unforgivable curses! spell_list= ["Crucio!", "Avada Kedavra!","Imperio!", "Expelliarmus!"] for spell in spell_list: if spell == "Avada Kedavra!": ! print "You're dead already!" elif spell == "Imperio!": ! print "You lost control of your mind!" elif spell == "Crucio!": ! print "I can feel your agony!" else: ! print "No unforgivable curses were cast upon you!"
While Loop while True: ! print "You're in an infinite loop!"
Using Modules import math print math.factorial(999)
Writing Modules lib.py def say_hello(): ! print "Hello Python!" greet.py import lib lib.say_hello() And yes, pydoc works on custom modules!
The Python Arsenal! Notable frameworks, modules and tools! Django wxWidgets PyQT / PySide Numpy Celery Google App Engine BeautifulSoup Shovel Python for Android Kivy
The Zen of Python import this
import antigravity
